Answer:
c
Step-by-step explanation:
I just need the points out of this
1. First calculate the positive root of the quadratic using your preferred formula. I got a solution
. That gives you the distance the ball traveled from d=0 (small hill). So the answer is A.
2. The domain is [0,2.121...]. The range is from 0 to the max height. The d for which the ball is the highest is given by the formula x = -b / 2a = -3.3/(-3.2) = 1.031... so the max is 1.902... So the range is [0,1.902...] So the answer is C.
